A series of shorter works composed by Christian Wolff written to explore the process of practicing and working within specified limits, exercises for both the composer and the performers, recorded live in Berlin in 2000 by an ensemble directed by Peter Ablinger and including Wolff on piano & melodica, Robin Hayward on tuba, Anette Krebs on guitar, &c.

"'Exercise' indicates relatively shorter pieces in which the process of work, of practicing and of trying things out within specified limits, in short a kind of discipline in process, are being attempted. I regard them as both exercises in composing and for performers, especially as the performers function as members of an ensemble."-Christian Wolff
